Can POPPY SEEDS cause a PRESUMPTIVE POSITVE OPIATE Screen?
Yes. There are numerous studies that have shown that poppy seeds can contain enough morphine to trigger a positive opiate screen. This is especially true at the 300 Opiate cutoff, but may occur at the higher 2000 Opiate cutoff also. A single poppy seed bagel or bun may contain enough morphine on the poppy seeds to be detected in a urine screen performed on the same or next day after consumption. Confirmation is required determine the concentration of morphine and codeine if any. No 6-MonoAcetylMorphine (6-MAM) should be present. The presence of 6-MAM is indicative of heroin use.
